How this notebook works

A quick tour of the Markdown features you can use in posts — callouts, math, footnotes, code, and wikilinks. Delete or edit this once you're comfortable.

This is a public lab notebook. Every post is a Markdown file in src/posts/. Write in Typora or Obsidian, drop the file in, and push — that’s the whole workflow. This first post is a cheat sheet for everything the site can render. See my first paper review for a real example.

Front matter

Every post starts with a small YAML block:

---
title: How this notebook works
date: 2026-07-11
tags: [embodied-ai]        # omit for an untagged note; use valuation too
summary: One line shown on the index.
draft: true               # true = visible in preview, hidden when published
---

Callouts

Obsidian-style callouts render as boxes. Type is anything after [!:

These are just blockquotes

Start a blockquote with [!note], [!tip], [!warning], [!danger], [!question], [!quote], and so on.

Watch the dollar signs

$ is the math delimiter. Digit-adjacent currency like $5B is safe, but when in doubt escape it — \$ always renders a literal $. Reserve bare $...$ for real math.

Foldable callouts

Add + or - after the type to make it collapsible. This one starts closed.

Math

Inline math like a2+b2=c2a^2 + b^2 = c^2 uses single $. Display math uses $$:

DCF=∑t=1NFCFt(1+r)t+TVN(1+r)N\text{DCF} = \sum_{t=1}^{N} \frac{FCF_t}{(1 + r)^t} + \frac{TV_N}{(1 + r)^N}

It’s rendered to HTML at build time — no MathJax loading in the browser.

Footnotes

Drop a reference inline[1] and it collects at the bottom of the post.[2]

Code

Fenced code blocks are syntax-highlighted at build time:

def value(fcf, r, g, n):
    """Two-stage DCF, terminal growth g."""
    pv = sum(f / (1 + r) ** t for t, f in enumerate(fcf, start=1))
    tv = fcf[-1] * (1 + g) / (r - g)
    return pv + tv / (1 + r) ** n

Tables

Standard Markdown tables work; align a column right with ---: to get tabular, right-aligned numbers:

Metric 2024 2025
Revenue ($M) 120 180
Gross margin 62% 64%

Linking between posts

Use [[filename]] or [[filename|link text]] to link to another post by its file slug — for example [[generalist-robot-policies]]. Regular Markdown links work too.

That’s everything. Replace this post with your own writing whenever you like.

  1. Footnotes are great for citations in paper reviews. ↩︎

  2. And for asides you don’t want cluttering the main text. ↩︎
